A3290KUA-T

The A3290KUA-T is a temperature-stable and stress-resistant precision Hall Effect Latch especially suited for operation over extended temperature ranges. Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device package over-moulding, temperature dependencies and thermal stress. The device include, on a single silicon chip, a voltage regulator, a hall-voltage generator, a small-signal amplifier, chopper stabilization, a Schmitt trigger and a short-circuit protected open-drain output to sink up to 25mA. A south polarity magnetic field of sufficient strength is required to turn the output ON. A north polarity field of sufficient strength is necessary to turn the output OFF.
